Words matter............................

As soon as certain topics are raised, the concrete melts into the abstract and no one seems able to think of turns of speech that are not hackneyed: prose consists less and less of words chosen for the sake of their meaning, and more and more of phrases tacked together like the sections of a prefabricated henhouse.
-George Orwell, Politics and the English Language

For an educational take down review of the latest Inaugural Address, one should really read this post from the Naked Capitalism blog.  To be fair, this same analysis could be applied to many speeches by many presidents.  Might make for an interesting inter-disciplinary college course.
